Next May wrap the sawo grafts with plastic to keep the moisture awake. The 15-day hose appears to be the small bulges of the root candidate on the incision. Gradually the bumps extends to roots. That's when he opened the hood and wrapped it in a plastic bag containing moss. About 1 – 2 months later the grafts can also be cut and planted on the ground or polibag.
' At most 2.5 months of grafting without media can already move planting, ' said Mei. It was obviously faster than a conventional sawo graft that took 8 months before the planting move. A non-media graft can also be done on small, cigarette-sized rods. Ordinary grafts can only be done on a trunk at least the size of a thumb.
In fact, Sawo can also be reproduced with the technique of bud and grafting. Alas, rootstock is hard to come by. Usually, the breeders connects the sawo with the lower stems of kecik, Tanjung trees, and . The problem availability of the three trees is rare. Innovations that may be expected can be a solution to accelerate the multiplication of sawo.
Broken branches
Success may grafted without media starting from the accident saw the broken Sawo branch. At that time he saw one of the branches of Sawo Ijen collection almost broke two. ' Almost 2/3 the trunk was broken. My estimate would have been 2-3 days again the branch was dead, ' says May. Not to be thought a few weeks, he found miracles. Instead of dying, in the former fault it appears swelling of cells.The cells that take them long to elongate form the roots. In fact, may in no way add any media or stimulant to the former faulting. From experience that may conclude the root of the Sawo branch is able to grow despite the wound wood tissue. In fact, the common graft technology only removes the kambium without damaging the wooden tissues.
May then conduct its own experiments by addressing a branch of SAWO to the wood network. ' Make sure the incision about some wooden tissues, ' says mother of two children. In order for rapid roots to appear may then give root stimulant hormones. The results are not in vain. Two weeks ago, in the former fault appeared the root protrusions. That means, ' even without the media, slices that hurt the wooden tissues can stimulate the growth of roots, ' said the woman from Manado.
According to Ir Edhi Sandra MSi, a plant physiologist at the Bogor Agricultural Institute, West Java, a media-less grafting technology with the help of hormones is very likely to be applied. ' Administering hormones Giberelin GA3, GA7 MIN, and GA12 is key to successful grafting without media. Because, Sawo belongs to plants that have a slow cell regeneration. The addition of these three hormones spur the acceleration of cell regeneration, ' says Edhi.
Edhi also says an oblique incision that injure the xylem tissue and meristem triggers the buildup of the auxin that descends from the tip. ' Accumulated in the amount of the number initiated the establishment of the root, ' said alumnus of the Bogor Agricultural Institute. Thanks to the stimulation of giberelin and the accumulation of auxin the process of grafting without media was successful.
' This is really a good technique and makes it easy to reproduce sawo seeds, ' said Friski Utama, a fruit breeders in Bogor, West Java. According to Edhi techniques grafting without media can be applied to other fruits. E.g. Mango. The principle when Giberelin spur cell multiplication and auxin triggers the formation of roots, grafting without media is worth the multiplication options. (Ari Chaidir/Peliput: Nesia Artdiyasa)
Sawo trees are hard to graft because of slow cell regeneration. Conventional graft technique takes 8 months to bring up the roots.
Root Bulge appears 15 – 20 days of post-Enyayatan
Grafting without Media
- Make an oblique incision from the bottom to the top of 1 – 2 cm on the branches to be chopped. The bribe is done with a sharp knife and sterile as deep as 2/3 sectional
- Prepare a mixture of giberelin hormones GA3, GA7 MIN, and GA12, as well as traumatic acids
- Apply the hormone mixture to the plastic sheet
- Then slip the plastic into the incision.
- The scars of the incision with a clear plastic bag to maintain moisture
- Two-week lapse of root candidate will appear in the incision
- After the root is somewhat long, open the hood and wrap it with a plastic bag containing moss
- One to two months later the grafts can be cut and planted on the ground or polybags
